ROBERT E. GOLF, OI HIGHLAND CREEK, ONTARIO, CANADA.

BNOWPLOW.

Application filed April 21, 1923. Serial No. 683,701.

To all whom it may concern: 'Be it known that I, Roam E. com, a subject of the King of Great Britain, and resident of High and Creek, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Snowplows, as described in the following specificatiomand illustrated in the accompanying drawings, that form part of the same.

The principal objects of the lnventlon are, to devise a machine which will effectively clear the snow from the highways irrespective of the condition of snow, thereby. maintaining open highways for traiiic at all'seasons of the year.

A further object is to devise a simple and efiicient mechanism which may beoperated at the minimum cost.

The principal feature of the invention consists in the novel arrangement of a lurality of vertically dis osed cutter mem rs adapted to cut into t e snow at whatever height it may be and to pass the snow cut thereby, into a succession of fan members to finally project the snow clear of the hi hway.

n the drawings, Figure 1 1s a plan v1ew of my improved machine, a POItlOIT of the top casing being broken away'to disclose one of the cutter members.

Figure 2 is a side elevational view.

Figure 3 is an enlarged detail of one'of the supplementary passing members.

Figure 4 is a diagrammatic plan vlew of a slightly modified structure.

Figure 5 is a diagrammatic plan of a further modified structure.

This device is adapted to be used upon the forward end of a vehicle and a frame structure, in the form of a pair of bars 1, extends forwardly from the motor, being adjustably supported by the wheels 2.

Mounted between the bars is a high power 'blower 3 which may be either in a single or double form, the double being shown and said blower is operated from the motive power of the vehicle or by a separate motor.

Forward of the blower and supported upon a suitable frame at the front endof the bars 1, are a plurality of rotary cutters 4 vertically journalled in a casing 1 open at the front. These cutters are preferably formed with spiral blades 5 arranged upon supporting drums 6 and are geared to operate in pairs rotating inwardly.

A serrated ice cutting blade 7 is arranged at the bottom of the open casing extending completely across the machine, being adaptblower 3.

The drums 6 may if desirable be provided with an arrangement of radial spikes 10 to serve in breaking up large chunks of ice.

These s ikes being arranged at the bottom end of t e cutters 4 and t e said cutters are made sufliciently high to cut away any ordinary snow bank and they will effectively cut into any depth of snow.

The snow is passed from the cutters into the beaters 8 and from there into the fans 9 to the blower 3. The blower directs the snow through the transverse pipe 11 from which it is discharged, either to the side of the road or into wagons.

ure 3, the beaters 8 are provided with a spiral flange 12 to take the snow from the In the detail enlargement shown in Figupper portion of the rotary cutters and feed x it downwardly to the entrance to the fans.

Such a spiral feed device may be arranged to work transversely of the machine if desired to clear the machine of ice, or even carry the snow to the blower.

In the diagram shown in Figure 4 the four cutters are arranged in the frame and in front of these cutters are arranged a pair of rotating cutter blades 13 which break down the snow in high banks before it is caught by the vertical cutters which pass it in through the fans and central blower.

In Figure 5 is shown a simple form of small machine where two vertical cutters are used to throw the snow into a single acting centrally arranged fan.

A snow plow such as described is carried on the end of a truck and when operated at proper speed will cut away any kind of snow and effectively discharge it wherever the discharge pipe may be directed.

What I claim as my invention is 1. A snow plow, comprising, a plurality of vertically journalled rotatable cutters, fan members mounted centrally between and immediately to the rear of each pair of,cutters and adapted to pass the snow received from'the cutters, and a central blower fed by said fan members and adapted to discharge thesnow. i

2. A snow plow, comprising, a rigid frame adjustably supported, a casing se: cured to the front end of said frame being open at the front, vertical rotary cutters journalled in said casing and arranged in j pairs, the members of each pair turning inwardly to cut the snow and throw it into the casing, conduits arranged to the rear of said cutters adapted to direct the snow backwardly, fans in said conduits, and retary means for discharging the snow delivered from said conduits clear of the'machine.

3. In a snow plow, a rigid frame, a cas ing supported from said frame and open at the front and having a plurality of journals arranged at the top and bottom, drums supported on said journals and having radial cutter blades, spikes secured to the drums adjacent to the bottom'between said cutter blades, means for rotating said ,drums to operate in pairs, fans arranged to the rear of said pairs of drums, and means fordischarging the snow thrown rearwardly by the said fans. I

4. A snow plow, comprising a rigid frame,

a pair of wheels adjustably supporting said,

frame, means for raising and lowering the frame in relatlon t0 the wheels, an enclosed 1 discharge fan --j0urnalled transversely in the frame, a casing arranged at theforward end of the frame andhaving openings communicating with said discharge fan, and rotary cutters vertically journalled in said open casing.
